I would love to. Thank you for reaching out.
The code below produces this error message:
"File "C:\Users\rober\ings\clean_recipe_text.py", line 14, in clean_recipe_text
with open("temp/fraction_free_recipe.txt", "r", encoding='utf-8') as decimal_recipe:
FileNotFoundError: [Errno 2] No such file or directory: 'temp/fraction_free_recipe.txt'
PS C:\Users\rober\ings> "
Fraction_free_recipe is the next to last text file produced by this series of functions.
The first function works fine. It produces the text file “recipe_contents.txt,” but the chain-of-events ends there.
The second function depends on_recipe_contents.txt to produce vulgar_free_recipe.txt (with vulgar meaning unicode).
The third function depends on vulgar_free to produce fraction_free_recipe.txt. The fourth functions depends on fraction_free, meaning all fractions and preceding integers - if they exist - are now converted into decimals.
There just are not any videos or examples in the docs with comparable requirements. And I have reviewed as many as possible, dozens at this point. I would appreciate some instruction on how to proceed. I should note I imported the Python code for convert_unicode_fractions(), convert_regular_fractions() and clean_recipe_text() from modules I wrote that work fine in other contexts. Any constructive feedback would be greatly appreciated.
Thank you.
